SUPERVISION. ACCEPTANCE AND USE OF THESE ITEMS SO CERTIFIES.
Chemical Based Products
DO
Safety
- Wear safety glasses.
- Wear rubber gloves if skin contact is possible.
- Have clean water on tap to wash any spilled chemicals off skin.
- Wash your hands after using heavy liquids.
- Use with good air ventilation under a fume hood.
- Observe good laboratory practice and normal precautions.
Heavy Liquid Separations
- Use only plastic or glass containers and implements.
- Use only benzyl benzoate to adjust the density of heavy liquid.
- Use only benzyl benzoate to wash minerals after separation.
- Check the density of your heavy liquids before using.
- Clean or deslime minerals before separation with Methylene
- Iodide, Bromoform or Acetylene Tetrabromide heavy liquid.
- You can recycle/reclaim chemical based heavy liquids.
- Contact a disposal service, do not pour down the drain.
DO NOT
Safety
- Do not ingest heavy liquids.
- Do not smoke or eat where heavy liquids are used.
- Do not allow any heavy liquids to contact eyes.
- Do not allow regular skin contact with heavy liquids.
- Do not continue to wear clothing contaminated with heavy liquids.
Heavy Liquid Separations
- Do not use metal containers, spatulas or other metal implements.
- Do not allow heavy liquid to come in contact with alkaline materials.
- Do not use wet mineral samples, or samples with a high slime content.
- Do not allow heavy liquids to evaporate, unless the density is rechecked.
- Do not discard heavy liquids into the environment.
Water Based Products
DO
Safety
- Wear safety glasses.
- Wear rubber gloves if skin contact is possible.
- Have clean water on tap to wash any spilled SPT/LST off skin.
- Wash your hands after using SPT/LST heavy liquid.
- Observe good laboratory practice and normal precautions.
Heavy Liquid Separations
- Use only plastic or glass containers and implements.
- Use only deionized or distilled water to adjust SPT/LST heavy liquid.
- Use only deionized or distilled water to wash minerals after separation.
- Check the density of SPT/LST heavy liquid before using.
- Clean or deslime minerals before separation with SPT/LST heavy liquid.
- Keep laboratory temperatures above 20° C to prevent SPT/LST crystallization.
- Recycle SPT/LST heavy liquid.
DO NOT
Safety
- Do not ingest SPT/LST heavy liquid.
- Do not smoke or eat where SPT/LST heavy liquid is used.
- Do not allow any SPT/LST heavy liquid to contact eyes.
- Do not allow regular skin contact with SPT/LST heavy liquid.

Heavy Liquid Separations
- Do not use metal containers, spatulas or other metal implements.
- Do not use saline or contaminated water to prepare SPT/LST heavy liquid.
- Do not use saline or contaminated water for washing mineral samples.
- Do not mix SPT/LST heavy liquid with other chemicals or different heavy liquids.
- Do not allow SPT/LST heavy liquid to come into contact with alkaline materials.
- Do not use wet mineral samples, or samples with a high slime content.
- Do not allow SPT/LST heavy liquid to evaporate, unless the density is rechecked.
- Do not chill SPT/LST heavy liquid below 20° C. This may cause crystallization.
- Do not discard SPT/LST heavy liquids into the environment.
